Inside /etc/openvpn/up.sh there is slight chance to make resolver configuration file (/etc/resolv.conf) invalid when ${DOMAIN} variable is not properly set. Then only keyword "domain" without value appears in /etc/resolv.conf and this can cause problems within resolving. Example: $ rc-service openvpn start [...] $ cat /etc/resolv.conf # Generated by openvpn for interface tap0 domain nameserver A.B.C.D $ host alice.in.wonderland host: parse of /etc/resolv.conf failed One possible solution to avoid this behaviour follows (patching /etc/openvpn/up.sh): 47c47,49 < DNS="${DNS}domain ${DOMAIN}\n" --- > if [ -n "${DOMAIN}" ] ; then > DNS="${DNS}domain ${DOMAIN}\n" > fi Using net-misc/openvpn-2.1_rc15 in client mode.
